Firearm receiver

ABSTRACT

The invention relates to a firearm and is a device for attaching the barrel to the receiver, for which the breech attachment unit is made in the form of a compressible clamp connection, the slot of which is located in the upper part of the receiver, and the upper part of the receiver itself allows to install and fix the sights on it.

TECHNICAL FIELD

The invention relates to guns technology and can be used in firearms.

PRIOR TECHNICAL TIER

Known methods of attaching the breech of the barrel in the receiver, forexample, U.S. Pat. No. 3,731,418A, US20140165444A1. These designs have aclamp connection with a slot in the lower part of the receiver, whichmakes it difficult to install the barrel and complicates the design.

Known solution with a clamp connection with a slot in the upper part ofthe receiver RU2588922 C2, in which the installation of sights iscarried out on an additional part, which also complicates the design.

DISCLOSURE OF THE INVENTION

This invention solves the issue of securely fixing the barrel in thereceiver and facilitating the manipulation of its installation.

To achieve the specified technical result, the receiver of the firearmhas an attachment unit of the barrel's breech, made in the form of acompressible clamp connection, the slot of which is located in the upperpart of the receiver, while the upper part of the receiver is the basisfor installing and securing the sights.

BRIEF DESCRIPTION OF THE DRAWINGS:

The essence of the invention is explained by sketches, where:

on FIG. 1—shows the external and axonometric views of the receiver withthe installed barrel and sight; the diagram of the installation andfixation of the barrel in the receiver; installation of the sight;

on FIG. 2—shows the appearance of the receiver, sections A-A, B-B;

on FIG. 3—shows the appearance of the receiver with the installed barreland sight; sections C-C, F-F, local view D;

on FIG. 4—shows the appearance of the receiver with the number oftightened parts, which is more than two, sections V-V, S-S;

on FIG. 5—shows the appearance of the receiver with the installedbarrel, when the receiver has two or more compression parts, anaxonometric view, a diagram of the installation and fixation of thebarrel in the receiver.

IMPLEMENTATION OF THE INVENTION

Receiver 2 (FIG. 1, 2, 3) for attaching the breech 1.1 of the barrel 1(FIG. 1) contains an attachment unit 3 (FIG. 2, 3), the breech of thebarrel 1.1 (FIG. 1), which is a compressible clamp connection,

including the channel 3.1 (FIG. 2), a longitudinal slot T (FIG. 2, 3),made on the compressible section 3.2 (FIG. 2, 3) of the upper part 2.1(FIG. 2, 3) of the receiver 2 (FIG. 2), while the upper part 2.1 allowsto install and fix the sights 18 (FIG. 1, 3).

Barrel 1 (fig.1) is placing with its breech 1.1 (fig.1,3), according tothe diagram in FIG. 1 in to the channel 3.1 (FIG. 2, 3). Further occursthe compression of the compressible part 3.2 (FIG. 2, 3) with the helpof part 11 (FIG. 1, 3), passing through the hole 3.3 (FIG. 2), while theslot T does not close.

A variant of the receiver 4 (FIG. 4, 5), when the number of partscompressing the clamp connection is two or more pieces, has anattachment unit 5 (FIG. 4) of the breech 1.1 of the barrel 1 (FIG. 5),similar in structure to the unit 3 (FIG. 2, 3), except that there aretwo or more transverse holes 3.3 (FIG. 4).

1. Receiver of the firearm, characterized in that the attachment unit ofthe barrel's breech is made in the form of a compressible clampconnection, the slot of which is located in the upper part of thereceiver, while the upper part of the receiver is the basis forinstalling and fixing the sights.
 2. Receiver according to claim 1,characterized in that the number of parts compressing the clampconnection is two or more pieces.
